What is color zipper for?

As implied by the name, color zipper is colorful. But which part of it is colorful anyway? People might think of zipper pull, tape, or slider maybe.

Actually, a zipper's teeth can be colorful too. More precisely, it can be “multicolored.” Some people would not like their multicolored jackets to go with self-colored zippers. For matching up, color zipperis then used.

We can see them on different colored sweater or stuffed dolls and so on. Some of them have multicolored tapes, and some have multicolored teeth. And most of them are commonly plastic and nylon zippers.
